Description

in org.apache.commons.io.FileUtils

Commons Fileupload uses at least the io's FileCleaner.track() method.
Unfortunately, they just use the plain java File.delete() method and not a more
sophisticated delete as offered in this package.

Especially, if servers running the FileUpload are sitting in DMZs and forward
all personal/private uploaded information in another (DB-)server behind another
firewall, one would not want that if the DMZ machine gets hacked, all previous
uploads that are supposedly deleted still can easily be found on the disk by a
not even that skilled attacker.

Therefore, it would be great to have a pgp-wipe alike secure delete method here!
it would overwrite the file multiple times and probably, it this should be
spawned as a separte thread since that may take longer than a state-of-the-art
GUI would want to wait for such an action to complete.
